On March 15, the day Tegnell wrote Tull they had landed on option three, Tegnell said the Public Health Agency’s “main tactic” was not herd immunity, adding that its goal and herd immunity were “not contradictory.” But in public, Tegnell frequently argued that herd immunity was “definitely not” a goal. As recently as Nov. 18, Minister of Health and Social Affairs Lena Hallengren said that the idea that Sweden had pursued a herd immunity strategy was a “rumor.”
The day before his correspondence with Tull, Tegnell forwarded an email to his Finnish counterpart, Mika Salminen, which contained a recommendation from a doctor to allow people to become infected with COVID-19. “One point would be to keep schools open to reach herd immunity more quickly,” Tegnell wrote.
Salminen said his agency had ultimately rejected such an approach, realizing children would still spread the virus, whereas closing schools could limit the disease’s impact on the elderly by about 10 percent. Tegnell, who still thought that quickly achieving herd immunity was the best strategy, responded: “10 percent might be worth it?”
The next day, Tegnell forwarded a study on Italy’s experience with COVID-19 to Jan Albert, a professor of microbiology, who was part of a coronavirus expert group assembled a few weeks earlier by the Karolinska Institute, a university and the center of Sweden’s medical research community. Tegnell pointed to what seemed to be a “flattening of new cases” there.
Albert replied: “Exactly. But most people think it’s just the lockdown. How much [is because of] lockdown and how much [is because of] herd immunity is really the key issue.” Tegnell answered: “If anyone had time, you should look at the various lockdowns that have been made and what the development looks like afterwards. I believe more in herd immunity.’’
Tegnell remained convinced that a rapid spread of the virus would shield Sweden, a belief that seemed to lead the country’s whole response to the crisis. A month after corresponding with Tull, Tegnell said Stockholm could achieve herd immunity in May. Three weeks later, he said: “In the autumn there will be a second wave. Sweden will have a high level of immunity and the number of cases will probably be quite low,” a claim he repeated into mid-October.
Carlson, Tegnell’s boss, echoed on Aug. 30 what Tegnell wrote Tull: “It is not about us sacrificing a lot of people to achieve immunity. This model was the only one that was feasible. Our assessment has proven to be correct. The strategy must last over time. We are one of the few countries with a limited spread of infection, unlike several countries in Europe where the infection returns sharply.”
It didn’t work out that way. Sweden is facing an increase in cases, hospitalizations, and deaths. On Nov. 5, the country reached the grim statistic of 6,000 deaths. In the six weeks since, nearly 2,000 more have died. In the week ending Dec. 18, Sweden registered 479 new deaths, more than Norway has during the entire pandemic.
